Lea Márquez Peterson currently serves on the Arizona Corporation Commission and is the past Chairwoman.  During her tenure, she has fought hard for affordable utility rates and has focused on ensuring energy reliability.  She was appointed by the Governor in 2019 and later won election to a four year term in 2020 and in 2024.  Lea is the first Hispanic woman to serve in a statewide seat in the history of Arizona and is the only Commissioner based outside the Phoenix area.

Lea has established a reputation on the Commission as a knowledgeable commissioner who is known for her fairness to consumers and utilities. She has focused on ensuring that Arizona has a reliable energy grid at the most affordable rates. She is concerned with any vote at the Commission that will impact the ratepayer- especially those who are vulnerable and who may be facing financial challenges.

Lea previously owned a chain of gas stations and convenience stores in the Tucson area putting many people to work.  Additionally, she served nearly ten years as the President of the Tucson Hispanic Chamber – one of the largest chambers in the state.
